Question

What is the Intelligent Dynamic Noise Reduction (iDNR) in Bosch cameras?

Answer

Intelligent Dynamic Noise Reduction (iDNR) in Bosch cameras is an advanced feature that dynamically reduces video noise while optimizing image quality. It helps improve low-light performance, reduces the storage and bandwidth needed for video footage, and ensures that important details are preserved even when noise reduction is applied. This makes it particularly valuable in security and surveillance applications where clear images and efficient data handling are essential.

iDNR gives the camera the ability to analyze the scene and determine if it needs the resolution assigned to it or reduce the bandwidth for the time there's no activity in the scene. This is a great bandwidth reducing feature of the camera.

Intelligent Dynamic Noise Reduction (iDNR) is an advanced feature that leverages CBIT technology. 

iDNR reduces noise and bit rate by analyzing light levels and Content Based Imaging to change the type of compression being utilized automatically:

• Temporal Compression
• Spatial Compression
